Summary
node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, node-tar coerces all-digit PAX path and linkpath values in src/pax.ts to JavaScript numbers, causing downstream path handling such as normalizeWindowsPath(entry.path).split('/') to throw an uncaught TypeError.
This issue is fixed in version 7.5.18. This vulnerability occurs when the library incorrectly converts specific archive path values into numbers, leading to an error during subsequent path processing.
An attacker could exploit this to cause the application using node-tar to crash, resulting in a denial of service. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L).
Weakness: CWE-843.
Affected products named by the advisory: Confidential Compute Attestation; Cryostat 4; Exploit Intelligence; Migration Toolkit for Containers; and 35 more.
